subwoofer update question - Click HERE for Original Thread
tylercv
Hey guys I have an old subwoof that was passed down from my uncle and has been pounded away for a few years. It is a BSR DR-SW15X2. The box is in great shape. The speaker still sounds all right but I think that it might be time for it to replaced. Here are the outside dimensions of the box-- 24.5" x 20" x 13.5". It has a DVC 15" speaker.
Do you all think that it would benifit from "spikes" (right now it just has plastic feet). If you all think that I could benefit from just building a new box that would work too, but I would rather take the cheaper route. I figure that I will just recover it with the same veneer as the rest of my speakers. Sorry that there are so many questions, if you all want pics of the sub I'll grab a digi cam from work tommorrow, but I need someone to tell me how to post pictures.

Also what would be a nice cheap amp to power this.

Thanks guys

When the driver's ok, I wouldn't replace it ;)

Nice, cheap amps: Parts Express 300-794 or Parts Express 300-792

Just build the amp in a seperate case.

it's an old paper cone an it sounds ok except for the air leak ( the foam has started to decentigate (crazy spelling). Can I just fix the foam. What affect do you get from using spikes.

Thanks again

The foam can be repaired or replaced. There are speaker-repair shops but I don't know them in the States ;)
Just try to find some of them and ask what a repair would cost. Otherwise it is better to replace the driver but then you'll have to look for a driver that's suited for the enclosure you already have (or start from scratch).

Spikes are the least of your problems now, air-leaks are a no-no, but they could at the end make some difference, depending on the surface your sub is standing on.

Hey, I found this thread on Google. A year or two ago I saw one of these at a garage sale for $40 I think. I went home, thought about it, went back to buy and it was gone. I saw them for $50-$150 on eBay.

Over the weekend I got one at Goodwill for $5! And it works!!

I'd love to know more about it if anyone can help. Like is it any good? :xeye:

If I had more time, more money, fewer expensive hobbies and didn't have this tin ear, I'd be an audiophile too. ;) My maximum investment limit in this system is probably another $5 or so for now.

I like the vintage style and you can't beat the price, but how do they perform compared to "modern" subs? My receiver has a sub pre-out but I don't have a sub amp. The sub has a built-in crossover and you run the speaker wires from the receiver to the sub and then to the speakers. What are the pros and cons of this type of hookup? I mean, besides the "pro" that I don't have to buy a sub amp... I do have a spare amp if I should do something different.

I've got an ~18-year old Kenwood system and couldn't tell you anything about it without looking at the manuals. The speakers are probably ~12" 3-ways. The receiver is from ~1995 and is their 2nd best Surround Sound unit. The spare amp is the original from the mid-80s.

Finally, since nobody posted pics for Tyler, I've mooched these off eBay:




thanks

Let's see if I can attach 3 pics at once

nope, have to do them one at a time. And one of them is too big.
